Microsoft has taken a significant step forward in enhancing the user experience of Windows 11 with the release of the April 2026 optional preview update (KB5083631). This update, aimed at versions 24H2 and 25H2, not only introduces a handful of new features but also addresses a multitude of long-standing issues that have frustrated users for years. The focus on performance and reliability marks a pivotal moment for the operating system, as Microsoft seeks to rectify complaints about memory usage and visual inconsistencies.
File Explorer finally stops flashing white and hanging
One of the most notable improvements is the resolution of the infamous “white flash” bug in File Explorer. Users who prefer dark mode have often found themselves startled by bright flashes when opening folders or resizing panes. This glitch stemmed from a mismatch between legacy background elements and the newer WinUI 3 dark mode styles. With the latest update, Microsoft has effectively eliminated this annoyance.
Furthermore, the update ushers in a significant overhaul of File Explorer’s codebase, replacing outdated components like the 31-year-old Properties dialog with modern WinUI 3 elements, although the timeline for these changes remains uncertain. Another enhancement ensures that View and Sort preferences are now preserved, addressing a common frustration where Windows would forget user settings when launching File Explorer from third-party applications.
Additionally, the reliability of the explorer.exe process has been improved, ensuring that it terminates properly after closing File Explorer windows, thus preventing unnecessary CPU usage from lingering processes.
Lifting a 30-year-old storage limit and boosting system performance
In a bid to enhance system performance, the April 2026 update tackles several critical areas. Notably, the “Delivery Optimization” service, responsible for downloading updates and apps via peer-to-peer sharing, has been optimized to reduce memory leaks and excessive RAM consumption. Users can expect a more efficient experience as this service operates in the background.
Moreover, the boot sequence has seen performance enhancements, allowing startup applications to launch more swiftly, thereby reducing the time it takes to get to the desktop and start working. Perhaps the most groundbreaking change is the lifting of the 32GB formatting limit for FAT32 volumes, which has been a relic since the days of Windows 95. Users can now format FAT32 volumes up to a remarkable 2TB, a long-awaited upgrade.
Taskbar, Microsoft Store, and general reliability fixes
The update also brings essential reliability improvements to the Windows shell. Users who have experienced issues with the Taskbar, particularly with the system tray area appearing empty after sign-in, will find that Microsoft has made strides in enhancing its reliability. Additionally, foundational code fixes aim to prevent crashes of explorer.exe during interactions with Task View and taskbar menus.
Other noteworthy quality-of-life improvements include:
- Microsoft Store fixes: The update addresses several persistent download and installation errors, notably errors 0x80070057, 0x80240008, and 0x80073d28.
- Windows Hello issue: A bug that caused Windows Hello Fingerprint data to be lost after major OS upgrades has been resolved, ensuring biometric data remains intact.
- Remote Desktop scaling: Improvements have been made to the Remote Desktop Connection security warning dialog, enhancing its display on multi-monitor setups with varying DPI scaling.
- Color Profile consistency: Enhancements ensure that custom color profiles for supported monitors remain persistent, aiding digital artists and creators.
- Typing and Input: The update improves the continuity of the “Fluid Dictation” feature in voice typing and enhances keyboard navigation reliability when using the emoji panel.
When is the next Windows 11 update?
Currently, these enhancements are available as part of the optional KB5083631 preview update for users who actively seek out updates. For those who prefer to wait for stable releases, the comprehensive improvements are set to be included in the upcoming Patch Tuesday update, scheduled for May 12, 2026. This mandatory security update will bundle these performance gains and additional features, further solidifying Windows 11’s trajectory towards improved functionality and user satisfaction.
